Assuming https://www.perfectduluthday.com/2021/06/03/june-of-71-anderson-furniture-remodels/ is the same building, then I would bet a lot of money that stripping those tiles would expose you to asbestos. Asbestos was so common in the 1970s for this sort of build that I'd be surprised if the original advert poster wasn't knowingly putting people at risk.
